Since today morning was wet, I planned my commute at the end of the day.
On middle of the ride got a rear flat. After removing the tube tried to inflate it to figure out where it was ..... Pump pump pump and nothing....????
Gosh... pump broken? Tried to inflate the spare tube and ohhh, not a pump issue. Looked closely the flat tube and couldn't figure out what was going on.
Did a visual and touch inspection of the tire and since couldn't find anything installed the spare tube and inflated.
All good, lets move on. After some half mile I now notice the front one seems losing pressure

....
Maybe time to call home for a ride...
Stopped and inflated the front one and waited a bit and seems ok.
Ended up riding some 10 miles home and was fine
Floor pump and is at 70 and rear 80 psi. Lets see tomorrow how the front one will be.
As for the rear tube, try to inflate and same. then I noticed two big cuts that looks pinch cuts since I pedaled to a safer place while flat.
I noticed a small on outer side of the tube that should be where it started.
For the front one, no idea why lost pressure...
